论文摘要
本说明研究了无线网络控制系统中的状态估计，并具有防止窃听的保密性。具体而言，传感器通过合法的用户链接将系统状态信息传输到估算器，而窃听器偷听了这些数据，将这些数据独立于用户链接。每个连接可能会受到数据包损耗的影响，并由有限状态的马尔可夫通道（FSMC）建模，这是一种广泛用于设计无线通信系统的抽象。本文提出了一个新颖的卑鄙平方英语预期保密性的新颖概念，并描述了秘密参数的设计，要求用户均方根估计误差（MSE）被界限，并且窃听MSE的MSE无限。我们在一个推车上的倒置的示例上说明了开发的结果，其参数是通过暴露于Eavesdropper的无线链接进行远程估计的。
This note studies state estimation in wireless networked control systems with secrecy against eavesdropping. Specifically, a sensor transmits a system state information to the estimator over a legitimate user link, and an eavesdropper overhears these data over its link independent of the user link. Each connection may be affected by packet losses and is modeled by a finite-state Markov channel (FSMC), an abstraction widely used to design wireless communication systems. This paper presents a novel concept of optimal mean square expected secrecy over FSMCs and delineates the design of a secrecy parameter requiring the user mean square estimation error (MSE) to be bounded and eavesdropper MSE unbounded. We illustrate the developed results on an example of an inverted pendulum on a cart whose parameters are estimated remotely over a wireless link exposed to an eavesdropper.
